FD Calculator

📐 How It Works

Where P = Principal, r = Annual interest rate, n = Compounding frequency per year, t = Tenure in years. More frequent compounding = slightly higher returns.

💡 Pro Tips

• 1Senior citizens get 0.25–0.5% extra on FDs — check if your parent qualifies.
• 2Tax-saving FDs (80C) have 5-year lock-in; interest is taxable unlike PPF.
• 3Compare small finance banks — they often offer 0.5–1% more than large banks.
